2 SHEETSSHEET 2 NTY WILLIAM DAIJTON, 0F SCHENECTADY, NEW YORK.

WORKSHOP-VENTILATOR.

To all whom t may concern: f

Be it known that I, WILLIAM DAL'roN, of Schenectady, New York, temporarily residing in Washington, in the District'of C0- lumbia, have invented a new and useful Improvement in l/Vorkshop-Ventilators, of which the following is a specification.

My invention relates moreV particularly to the novel construction of Ventilating means for a forge shop, or amanufacturing building, wherein large volumes of smoke or injurious gases are liberated by furnaces or manufacturing processes.

The objects of my invention are to provide a simple and effective formof a shop roof having one or more smoke or waste gas outlet ports or vents, and partition walls arranged, within the shop', with respect to the smoke vents so as to effect a continual upward and outward flow of smoke through the ports fromr the' building regardless of wind velocities or direction; another object is to prevent the'flowv of'smoke from'one interior section of the building to another and instead to cause an' immediate upward and outward flow of waste gases; a further object is to prevent a downward and inward flow of cold air through the vents and into thebuilding, thereby avoid a retardation to the upward and outward flow of waste gases.

In the` accompanying drawings forming part of this Specication: Figure 1, is a longitudina-l elevation of a' building, or workshop, adapted to exemplify an' application of my invention, part of the building is v 4 shown broken away to' illustrate avertical longitudinal lmid section thereof; Fig. 2, ,a transverse sectional elevation, on' an enlarged scale, taken on a vertical intersecting plane indicated by the trace, A A, in Fig. 1; Fig.' 3, anexterior elevation of a building showing -a modification of my invention adapting its application -to the form of building illustrated Awherein a horizontal roof section is disposed atk a considerable higher elevation than oppositely disposed sloping side roof sections; Fig. 1i, a 'transverse section thereof when taken -on a vertical plane indicated by the trace, B B; Fig. 5, a' longitudinal mid sectional elevation there-- y of is taken on the plane indicated by the trace, D D; Fig. 6, a transverse sectional elevation showing the application of my invention to -a building having a pair of oppositely disposed sloping roof sections; Fig. 7, a transverse sectional elevation giving all Patented Dec. 10, 1918.

exempliication when applied to a* roof,

formed of a plurality of flat and horizontally disposed roof sections.

In the practice ofmy invention, referring descriptively to the preferred arrangement when embodied in a work shop, or building, asexemplied by the accompanying drawings, I provide one or more elongated waste gas outlet ports, 1, la, 1b, 1, le, lf, 1g., which are preferably formed in asectionof abuilding roof under which smoke, vapors or other waste gases will naturally accumulate because of their buoyancy. VA roof, or, section thereof, adapted to the application ofmy invention may be inclined at any desirable angle, as illustrated by thesloped roof sec'- tions, 2, 2a, 2b, 2d, 2e, 2f; 2g and 2h, shown in the several iigures. Frequently it is desirable for manufacturing purposes to construct a roof section nearly fiat and horizontal, as indicated by 2i, 2l; 2m and 2". A horizontal roof section may be disposed adjacent to a sloping roof section. Furthermore, it may be arranged between .two oppositely disposed ysloping sections', as indicated by the drawings. Aplurality of horizontalV roof sections, asQm and 2n, may be supported by a truss, 3, in usual manner, as in Fig. y7, and provided with an interposed outletr port, 1f. Two oppositely disposed outlet ports, f1?

and 1g, separate the two outer sloping roof rain from passing downwardly into the outlet ports, flat horizontally disposed port covers, 8, 8a, 8b, 82,8", 8f and 8g, are supported by upright struts, 9, 92.91), 9d, 9e, 9f and 9g, at a predetermined'dista-ncel above the corresponding ports and roof sections as illustrated. These ports are further sheltered from aV downward fiow of roof water by the corresponding flashing members, 10, 10, 10" c, f

10d, 103,101, 10g, 10h and 101.

'Manifestly the outlet ports may be made circular or rectangular as desiredk for convenience in construction. Preferably they are made oblong and disposed parallel with the building so as to give the greatest amount of ventilation at the least cost of construction. Their arrangement as illustrated has proved most eiiicient in practice. However, their constructioncan be modilied to meet special requirements without departing from the spirit of my invention.

As indicated by the broken darts in. FigzQ, outdoor air currents can pass freely in a horizontal direction over the ports and unf der *the port covers, in a manner to cause a fluid rareiication directly under the port and thereby induce an upward flow of yWaste gases that may have accumula ted under the roof in the vicinity of the outlet port.

The vertically disposed curtain-like partitions 6, vare shown to begin at a predetermined distance above the working licor, 12, so asftoy givel a clear working space on the floor. Their upper edges, 6g, eXtend upwardto the corresponding port for the purpose of guiding the gases upward to the port and to prevent cross currents of air from driving the waste gases from one section of the building to another, and instead cause hot gases from the furnaces, 18, 13a.

13b, and other sources, to rise upward, di-

rectly' to the outlet ports, 1. The inclined partitions, 14, 14a, 14:", 14d, 14 and 142 subdivide the space under the roof sections for the purpose of aidingthe vertical partitions to guide the gases upward and to reduce cross air currents through 'the upper sections of the building. The several partitions are preferably 'disposed parallel to the elongated ports, each other and to the sides ofthe building for convenience of 'construction and efficiency in operation asl an aid to the ventilatingoutlet ports and in preventing undesirable cross currents in the building. Such cross currents of air and waste gases are seriously objectionable because they carry furnace smoke from one section to all parts of the building. Instead, the partitions cause it to rise directly to the outlet ports formed in the roof. y

Outdoorai-r is admitted through the inlets, 15,1'5"L,15b,15 and 15e, formed in the side walls of thebuilding,preferably near the working floor level for lthe purpose of maintaining atmospheric pressure in the y building, at the workingk floor level and thereby induce a prompt upward iiow, of waste gases, toward the outlet ports.

lVhat l claim is:

1. In a factory buildinghaving alarga working floor lspace and a roof covering the same with Ventilating openings therethrough for the freeescape of-fumes above the roof, a means for preventing the flow of fumes laterally from one part of the building into another", and for inducing an upward movement of fumes from the' Working loor area, embodying side walls having air entrance openings near the Hoor level anda curtainlike intermediate partition extending down from the roof and terminating at its lower edge above the working floor space, the spaces at the top on both sides of said curtain-like intermediate partition being in free communication with the Ventilating openings.

2. In a factory building having a large working floor space and a roof covering the same with a Ventilating opening therethrough for the free escape of 4fumes above the roof, a means for preventing the flow of fumes laterally from one part of the building to the other and for inducing an upward movement of fumes from all parts of the floor area embodying external side walls extending to the roof and having air entrance openings near the loor level and a curtain-like intermediate partition extend'- ing down from the roof level and terminating at its lower edge above the working Hoor space, the upper edge of said partition extending acrossv the ventilating opening whereby the spaces on opposite sides of the partition both communicate freely with the rentilating opening.

3. A factory building having a large working floor space and embodying inclosing walls with air inlet openings, a roof forming a cover for the building and having an outlet'port for the free escape of fumes above the roof and a plurality of fume-guiding partitions within the building, said partitions extending substantially throughout the buildingy vabove the working floor space and converging toward Vand terminating at their upper edges in proximity to the port, whereby all the spaces defined by the partitions are open at the top to the outlet port and fumes rising in different parts of the building are guided to the'outlet port without opportunity for accumulation by lateral movement within the building above the working floor space. l

4.- A factory building having a large working) floor space and embodying inclosing walls with air inlet openings, a roof form ing 'a cover for the building and having an outlet port for the free escape of fumes above'the roof, a vertically arranged fume guiding partition extending from the outlet port down into the building to a point above the working lloor space and an inclined fume-guiding partition in the space between the 'vertical partition and side of the building, the spaces on both sides of said partitions being open to the outlet port at the top and to the working floor space at the bottorn, and said partitions extending substantially throughout the building above the working floor space.

5. A factory building having a large working floor space and embodying inclosing walls with air inlet openings, a roof forming a cover for the building, and having an llO elongated outlet port for the free escape of fumes above the roof, a fume-guiding partition Within the building extending substantially throughout the building above the working floor space parallel with the lon- 0 tition and the port for the escape of fumes,

said partition at its lower edge terminating above the Working oor space of the building, whereby fumes rising above said ioor space on either side of the partition Will be guided to the port and lateral movement of such fumes Within the building prevented.
